Как добавить доверенный сертификат привязки с URL-соединением?

Question

Я хочу добавить доверенный сертификат с URL-соединением, используя хранилище ключей. Ниже мой код ...

        try {
        val url = URL("https://-------.com")
        val sslCtx = SSLContext.getInstance("TLS")

        sslCtx.init(null, arrayOf<TrustManager>(object : X509TrustManager {
            override fun checkClientTrusted(chain: Array<out X509Certificate>?, authType: String?) {
                TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
            }

            private var accepted: Array<X509Certificate>? = null

            override fun checkServerTrusted(xcs: Array<X509Certificate>, string: String) {
                accepted = xcs

            }

            override fun getAcceptedIssuers(): Array<X509Certificate>? {
                return accepted
            }
        }), null)

        val connection = url.openConnection() as HttpsURLConnection

        connection.hostnameVerifier = HostnameVerifier { string, ssls -> true }

        connection.sslSocketFactory = sslCtx.socketFactory

        val keyStoreType = KeyStore.getDefaultType()
        val keyStore = KeyStore.getInstance(keyStoreType)

        val `in` = resources.openRawResource(R.raw.gd_bundle)
        keyStore.load(null, "12345678".toCharArray())

        Thread(Runnable {
            try {
                connection.connect()
                // Your implementation
                Log.e("http.responseCode", "" + connection.responseCode)
                if (connection.responseCode == 200) {
                    val certificates = connection.serverCertificates
                    println("cert added")
                    ca = certificates[0]

                    Log.e("getAlgorithm", "" + ca!!.publicKey.algorithm)
                    Log.e("getFormat", "" + ca!!.publicKey.format)

                }

                keyStore.setCertificateEntry("MEDITAB", ca)

                // Create a TrustManager that trusts the CAs in our KeyStore
                val tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm()

                val tmf = TrustManagerFactory.getInstance(tmfAlgorithm)
                tmf.init(keyStore)

                Log.e("SSSSSSSSSSSSS", "" + tmf.toString())

                // Create an SSLContext that uses our TrustManager

                context1 = SSLContext.getInstance("TLS")
                context1!!.init(null, tmf.trustManagers, null)


                if (connection.responseCode == 200) {
                    //                            InputStream in = getResources().openRawResource(R.raw.gd_bundle);
                    //                            System.out.println(in.read());
                    //                            String line;
                    //                            BufferedReader reader = new BufferedReader(new InputStreamReader(in));
                    //                            StringBuilder out = new StringBuilder();
                    //                            while ((line = reader.readLine()) != null) {
                    //                                out.append(line);
                    //                            }
                    //                            System.out.println(out.toString());
                    Executors.newSingleThreadExecutor().execute {
                        try {
                            Log.e("http.responseCodeeeeeeeeeeeeeeeeeeeeeeee", "" + connection.responseCode)
                        } catch (e: IOException) {
                            e.printStackTrace()
                        }
                    }


                }


            } catch (ex: Exception) {
                ex.printStackTrace()
            }
        }).start()

        connection.disconnect()
    } catch (e: IOException) {
        e.printStackTrace()
    } catch (e: NoSuchAlgorithmException) {
        e.printStackTrace()
    } catch (e: CertificateEncodingException) {
        e.printStackTrace()
    } catch (e: KeyManagementException) {
        e.printStackTrace()
    } catch (e: CertificateException) {
        e.printStackTrace()
    } catch (e: KeyStoreException) {
        e.printStackTrace()
    } catch (e: UnrecoverableEntryException) {
        e.printStackTrace()
    }

Как сделать вышеуказанный код общим для всех URL. А также я хочу знать, как проверить этот добавленный сертификат привязки доверия в устройстве?

Пожалуйста, помогите
